Photoexcitation of 50Cr, 53Cr and the Debye Temperature of Chromium

The random photoexcitation process of n‐capture γ‐rays was used for studying the decay properties of the 8888 keV level in 50Cr and a level at 7646 keV in 53Cr. The γ source was obtained from the Fe(n,γ) reaction. The scattering cross section σs from the 8888‐keV level was measured in the range 297 K–10 K and the Debye temperature of metallic chromium was found to be Θ=510±20 K. The result is compared with that obtained by other methods.
